Former presidents — they’re just like us (minus the generous pension, 24-hour-a-day Secret Service protection, dedicated presidential library and a few other perks that come to mind). If you want to keep something private, send an old-fashioned letter, advises former President Jimmy Carter. The 89-year-old former president told NBC News’ Andrea Mitchell in a new interview that he thinks the U.S. intelligence community is probably monitoring his communications, too. “When I want to communicate with a foreign leader privately, I type or write a letter myself, put it in the post office, and mail it,” he told Mitchell with a chuckle. “Because I believe if I send an email, it will be monitored.”
